[s-cars] Coupe Quattro Stereo Wiring

[Ben Swann]

I am adding a power AMP to my '90 Coupe Quattro and the amp will need fair
size + wire (10 Guage is what I am installing) to the battery.  Battery will
ultimately be moved to the trunk for AAN engine install, but for now would
like to route to existing battery, but not good access through the firewall.
When I install the battery in the trunk I will need to run a #2 or 0 wire
somehow, but this will be easier to do when the engine is out.

 

So wondering if any other good places to tap into with the #10 wire - fuse box
is easy to get to, but did not see a spare connector, but may be there if I
pull the box out.  I know on some other cars there is usually one spare large
spade connector good for 40 AMP.

 

Or is there a good place to route through tre firewall that I am not seeing,
and can get too without too much trouble.  Any BTDT?

 

The AMP will likely go in the trunk with the Subwoofer, as there is not good
room under the seat(would be nice) and even if I made a cutout, the cooling is
not good under the seat.  Any hidden areas behind panels?  Amp is about 9" X
12" Kenwood with Front, Rear and Center channels.

 

TIA
